LAMP-CHIMNEY.

SPECIFICATION forming part of Letters Patent N0. 792,473, dated June 13,1905.

Application filed February 1, 1904. Serial No. 191,449.

To all whmn it may concern.-

- Be it known that I, AARON P. STORES, a citizen of the United States,residing in Owego, in the county of Tioga and State of New York, haveinvented a certain new and useful Improvement in Lamp-Chimneys, of whichthe following is a description.

The present invention relates to improvements in lamp-chimneys for usein connection with incandescent gas-burners, but particularly of thattype in which the air is admitted to the outside of the mantle throughopenings in the chimney, although the invention is not limited tochimneys of that character.

The main object of my invention is to produce a chimney, preferably,though not necessarily, of mica, which will have combined with it theburner-cap and a support for the mantle, the whole being arranged toform a new article of manufacture which will be an entirety and can besold ready with the mantle in place for direct attachment to the burner.A further object is to provide means for supporting the mantle withoutthe need of the side rod heretofore used.

. A further object is to provide means for supporting the mantle withinthe chimney so securely that it will not be deranged in transportation.

In carrying out my invention I provide a chimney ofa transparentmaterial with a base-plate upon which a projection is carried, which mayconstitute a burner-cap and which extends into the chimney and serves asa support for the lower extremity of the mantle.

The upper end of the mantle is carried by a removable crossbar, so thatthe mantle may be removed and a fresh one substituted. The chimney, withthe projection and mantle, may be readily attached to the commercialform of burner by the removal of the cap from the latter, the chimneywith the mantle taking its place and being supported thereby withoutengagement with the gallery.

The chimney is preferably made of mica panels perforated near the bottomfor the admission of air to the outside of the mantle and supported upona metal base-plate which has a central opening adapted to surround theburner. This central opening connects with l a cylindricalprojection,which serves as a support for the lower end of the mantle,and carries the upper gauze, thereby forming a burner-cap. At the upperpart of the mica chimney is arranged a cross-bar of some metal notreadily affected by heat. The bar is formed at its center with a loop,from which the mantle is supported. The ends of the cross-bar arepreferably flattened and shouldered and engage Within rectangularopenings formed within a band which forms the upper edge of the chimney,whereby the flattened ends prevent the rod from turning and theshoulders prevent it from being displaced longitudinally. A removableextension, of metal or mica, fitting within the upper part of thechimney may be provided as a finish to the chimney and to increase thedraft, and this extension may be provided with inclined slots, whichwill engage with the cross -bar and upon the extension being partiallyrotated will cause it to engage with the sides of the rectangularopenings and will lock it firmly in place.

In order to better understand the nature of the invention, attention isdirected to the accompanying drawings, showing one embodiment of theinvention, and in which- Figure 1 represents a side perspective view ofa chimney in place upon a burner of Wellknown design. Fig. 2 is aperspective view of the upper band and extension, the two beingseparated. Fig. 3 is a top view of the chimney with the extensionremoved. Fig. 4 is a sectional View of the lower portion of the chimney;and Fig. 5 is a view of the upper part of the chimney, showing amodified Way of supporting the cross-bar.

Inall of the several views like parts are designated by the samereference-numerals.

As shown in Fig. 1, the chimney consists of a number of panels 1, ofmica, constituting the transparent portion, bent to the shape shown andsecured in position by uprights 2 and to a base 3 and an upper band 1.The mode of securing the mica panels to the uprights 2 and the characterof the uprights are described and illustrated in my Patent No. 700,991,of May 27, 1902.

The base 3 (shown in section in Fig.4) is upper portion is drawninward?at 8 and serves as a support for the upper gauze 9, which is insertedfrom below and is secured in position by elastic engagement with thesides oitheprojection7. Additionalmeans, however,

may be used to retain the gauze inposition. The lower gauze is carriedby the burner, as is well understood. same shape and size as theburner-cap and, together with the gauze; w hen used may take the placeof the cap.

the projection depending uponthe character of the burner used; micapanels 1 may be protected by alower band 10, which will rest within theflange 5* of the base; but this band is not absolutely essential, as thepanels may be in direct engagement with the flange. The uprights 2* areprovided With tongues 11-, whicharepreterably integral and which passthrough openings 12in the base. These tongues beingbent up; as shown inFig. 4', serve as a locking means for securing the base to the rest ofthe structure.

The lower end of the mantle 13 surrounds the projection 7, and its upperend is supported'i rom the middle of the cross-bar 14L, the ends or"which are supported by the chimney. This cross-bar takes the place ofthe usual side'rod carried by the burner-cap. Thesid 'e rod in burnersof the type in which the present invention is especially applicablebeingclose to the mantle is-subject to great heat and may becomedistorted or destroyed thereby.

As shown in Fig. 2, the upper band 4 ispro vid'ed withoppositely-arranged openings 1 5, withinwhich the extremities of thecross-bar 14 rest. The bar is formed of a round' rod or wire witlr theends flattened at 16, forming shoulders 16, andthe openings 1='5- arepreferably of rectangular sl1a-pe,so that thebar will not turn but thisconstruction'is not necessary. The openings are of less width-thantheshoulders 16, whicha'but against the inner surfaces of the upper ring 4and prevent horizontal displacement of the cross-bar.

As shown in Fig. 5, the cross-bar may pass through openings formeddirectly in the mica panels, each opening being provided, it desired,with an eyelet 17.

the cross-bar is not necessarily flattened; but theshould'ers 16 may beformed by upsetting-- the wire near each extremity.

The cross bar 14 is preferably made of nickel or some otherheat-resisting material and is formed near its centerwitha double Theprojection 7 is the The projection 7 it isto be understood, is soproportioned as to make a close fit with the burner, the size of Thelower edges of the In the modification 1 loop 18 for the purpose ofsupporting the mantle. The peculiar mounting of the crossba'rand theprovision of the latterwith a central loop is to securely hold themantle in place; irrespective of the position it may assume. The shapeof the loop is shown in Fig. 3 there being sufiicient space left betweenthe turns of the loop to permit the supporting-loop of the mantle to beslipped within thewire loop.

The extension 19 is preferably made of some light sheet metal-,.such asaluminium, or of sections of mica and is of the proper size 1 to readilyenter the ring 4:, a flange 2O serving to support the extension. Twoinclined or' the extension are adapted to engage with the ends ofthecross-barl i and upon the extenthe cross bar'i-n' position. Suitableclips-'22,

By

: todistort it and cause it to assume the shape 1 shown inbrokenlines-in Fig. 3, the other errtremity oithe cross-bar maybe readily inserted within the opening 1 5 and upon the pressurebeing removed thering will assume position; The extension may then be applied byintroducing it within the upper band to engage with the cross-bar, andupon the extension being partially turned it will be "locked inplace-and the cross-bar be secured in position. When thus assembledthechim neys, with the mantles therein, may be placed within boxesorotherwise packed and shipped, the purchaser merely having to attach theentire device to the burner in place of the burner-tip-without having tohandle the man'- 1 tie directly.

it is to be understood that the chimney is 5 supported entirely from theburner 24 by enjgagement oithe projection 7 therewith and withoutengagementwith the gallery.

If a mantle isto'be' replaced, the used one vserted.

It is to be understood that the chimney -may be made of glass, itdesired, and that ted without departing from the invention.
